The fair market value of the car is typically defined as the highest amount that a prospective buyer is ready to offer and that a seller is willing to accept in an open and unregulated market. In this situation, you have established the following:
Your friend is prepared to purchase it for $3,500.
Your own assessment does not exceed $3,000 as a fair price.
You are confident that no one in the market would be ready to pay more than $3,200 for the car.
In this context, the fair market value is determined by selecting the highest amount from these considerations. Consequently, the fair market value is $3,500, which coincides with the sum your friend is prepared to pay. Therefore, the correct option is:
$3,500.
